Detailed Description

template<typename T>
class GaugeField< T >

Gauge field class.

Stores and defines links between Lattice Field elements. Number of links is lattice.size()*NDIM, since for each point there is a link in all directions.

Parameters

fdir	std::array<Field<T>,NDIM> type element which stores GaugeField links in back to back direction wise ordering.

Template Parameters

T	Group that GaugeField consists of

Member Function Documentation

measure_plaq()

template<typename T >

double GaugeField< T >::measure_plaq ( ) const

inline

Computes Wilson action.

\begin{align} S &= \beta\sum_{\textbf{dir}_1 < \textbf{dir}_2}\sum_{X} \frac{1}{N} \Re\mathrm{Tr}\left[ 1- U_{\textbf{dir}_1 \textbf{dir}_2}(X) \right] \end{align}

Where \(\beta = 2N/g^2\)

Returns

double

reunitarize_gauge()

template<typename T >

void GaugeField< T >::reunitarize_gauge ( )

inline

Reunitarize Gauge Field consisting of \( SU(N)\) matrices.

Only defined for \( SU(N) \) matrices and Fields
